php頭重定向..不工作

我已經檢查並重新檢查，我不知道我做錯了什麼。沒有錯誤顯示出來，只是在我提交一個登錄頁面後，我沒有指向任何地方..任何建議？php頭重定向..不工作

頭：

<html> 
<head> 
<title><?php echo $title; ?></title> 
<style type ="text/css"> 


#top_links a:link, a:visited{ 
    width: 100%; 
    display: block; 
    font-weight: bold; 
    color: #FFFFFF; 
    background-color: black; 
    text-align: center; 
    padding: 4px; 
    text-decoration: none; 
    text-transform: uppercase; 
    border: none; 
    font-family: "Trebuchet MS", Helvetica, sans-serif; 
} 

#top_links ul{ 
    display: table-row; 
} 

#top_links li{ 
    display: table-cell; 
    margin: 0; 
} 

#top_links a:hover { 
    color: pink; 

} 

</style> 
</head> 

<body<div id="top_links"> 
<ul> 
    <li><a href="REGISTRATION_FORM&HANDLE.php">Register</a></li> 
    <li><a href="LOGIN.php">Login</a></li> 
</ul> 
</div>

的login.php文件：

<?php 

require_once('../../../secure_files/mysql_connect.php'); 
$title = 'Login'; 
include_once('header.php'); 
if(isset($_POST['validate'])) { 
    $errors = array(); 
    function validate_func($value, $msg, $val_type) { 
     global $link; 
     switch ($val_type) { 
      case 'string': 
       if(empty($value)){ 
        $errors[] = "You forgot to enter your email ".$msg; 
       }else{ 
        $value = mysqli_real_escape_string($link, trim($value)); 
       } 
       break; 

      case 'password': 
       if(empty($value)) { 
        $errors[] = "You forgot to enter your email ".$msg; 
       }else{ 
        $value = trim($value); 
       } 
       break; 
      case 'number': 
       if(!isset($value)||!is_numeric($value)) { 
        $error[] = "You forgot to enter ".$msg." or the value you entered is not a number."; 
       }else{ 
        $value = trim($value); 
       } 
       break; 
     } 
     return $value; 
    } 

    $email = validate_func($_POST['email'], "email", "string"); 
    $password = validate_func($_POST['password'], "password", "password"); 
    if(!count($errors) != 0){ 
      foreach($errors as $value) { 
       echo $value." <br />"; 
      } 
    }else { 
     $select_guest = "SELECT GUEST_INFO_ID FROM GUEST_INFO WHERE EMAIL = '$email' AND PASSWORD = sha1('$password') LIMIT 1"; 
     $exec_select_guest = @mysqli_query($link, $select_guest); 
      if(mysqli_num_rows($exec_select_guest) != 1) { 
       echo "You are not an authentic user, you are being directed to the registration page..."; 
       mysqli_close($link); 
       header("Refresh:3; url='REGISTRATION_FORM&HANDLE.php'"); 
      }else{ 
       $one_record = @mysqli_fetch_row($exec_select_guest); 
       setcookie('GUEST_INFO_ID', $one_record[0], 0, '/', '', 0, 0); 
       echo "You are an authentic user"; 
       header("Refresh:3; url='GUEST_MAIN_MENU.php'");    
      } 
    } 

} else{ 
?> 
    <div id="LOGIN_MAIN"> 
     <form action="<?php echo $_SERVER['PHP_SELF'];?>" method = "post" > 

      <div> 
      Email:<input type="text" name="email" id="email" /> 
      </div> 

      <div> 
      Password:<input type='password' name='password' id='password' /> 
      </div> 

      <div> 
      <input type='submit' name='submit' id='submit' value='Submit' /> 
      <input type='reset' name='reset' id='reset' value='Reset' />  
      <input type="hidden" name="validate" ID="validate" value="Reset" /> 
      </div> 

     </form> 

    </div> 

<?php 
} 

include('footer.php'); 
?>

和我的頁腳：

</body> 
</html>

可能的[如何修復]已經發送的頭文件「PHP中的錯誤」的副本（http://stackoverflow.com/questions/8028957/how-to-fix-headers-already-sent-error-in-php） – Jocelyn

的原因是，你的東西遙相呼應您設置的頭前。

任何頭必須在任何其他輸出有效之前。
見php-manual for header()

所以刪除

echo $value." <br />"; 
echo "You are not an authentic user, you a...";

或頭重定向之前的任何輸出，它會努力！

如果你想重定向AFTER用戶已經看到了響應，你將不得不使用JavaScript重定向！那麼這將是這樣的：

<script> 
// redirects after 3 seconds 
setTimeout(function(){ 
     window.location.href = "GUEST_MAIN_MENU.php";; 
    }, 3000); 

</script>

Sidecomment：
無論如何，我會推薦給測試用戶的憑據，而無需再次加載新的（或相同）的PHP腳本。看看javascript ajax！使用這種技術，用戶將停留在同一頁面上，並獲得更直接的迴應，即您的應用程序也可以對消息和重定向做出反應。
